摘要:
A connector (1) for an apparatus for reading smart card (C), having a body supporting brush contact elements (Bc1, Bcx) for electrically contacting the conductive pads of a chip on a card (C) inserted into the connector. The connector includes an electronic circuit connected to a least some of the brush contact elements (B) and connectable to the electronic circuit of the card reader. The electronic circuit on the connector includes an arrangement for controlling the insertion of the card (C) into the card reader and its withdrawal therefrom, and one of the brush contact elements (Bxc) is at a second predetermined potential and offset in relation to the other brush contact elements (Bc1) so that once the card (C) has been properly inserted into the connector, one of two events occurs when the card is withdrawn and before the other brush contact elements are disengaged from the conductive pads (C.sub.1) of the card (C) that they are contacting. Specifically, either the brush contact element (Bc.sub.1) at the predetermined potential and the brush contact element at a so-called earth potential are short-circuited, or the second potential varies with a magnitude no smaller than a predetermined threshold.

The invention concerns a connector of the shielded type comprising a socket (1) attached to a printed circuit board (CI) and a plug (7) designed to be mechanically and electrically coupled to socket (1). A first shielding component (2, 4) is extended by elastic locking projections (22) provided with hooks (24). Shielding (9a) of plug (7) comprises openings (90a) in which these hooks (24) engage. These projections (22) rub against shielding (9a) of plug (7) and establish a galvanic contact between shieldings (9a, 2, 4) of plug (7) and socket (1). They also assure a locking of the latter in the socket (1).

The electronic components, provided with a series of contact pins, are picked up out of a feed unit (50) by a pickup-and-insertion head (20) which travels along the Y axis to above a table (12) on which is mounted the printed circuit board, and which can travel along the X axis. The series of contact pins are pushed into the corresponding holes in the board after a visual inspection of the position of the contact pins and holes has been carried out. This visual inspection is carried out by a camera (70) which is fixed-mounted between the feed unit and the table (12), and by a camera (80) which is mounted in the vicinity of the head (20) and which can travel with said head.

The active connector for a chip card is made up of a component (1) for control of the reading-writing operations of the chip card (20) and a reading frame for the chip card comprising a support component (2) made of insulating material and receiving contact terminals of a first type (3) projecting from an upper plane (4) of the support made of insulating material in order to be in electrical contact with contact areas (5) of the chip card. The insulating support comprises a lower face (6) inscribing in a lower plane, from which, on the one hand, contact terminals of a second type (7) project so as to be in electrical contact with contact areas (8) of the component for control of the reading-writing operations of the chip card and, on the other hand, connection leg pieces (9) for connection onto a printed circuit, leg height (h) defining a space between the insulating support and printed circuit (15) such that the control component is housed between the lower plane of the insulating support and the printed circuit.
摘要:
An electric connector presenting an insulating casing with at least one axial cavity; an electric terminal retained inside the cavity by an elastic lance; and a first movable element which snaps onto the casing to determine correct engagement and prevent disengagement of the elastic lance and the terminal; the first movable element also presenting a second movable element interposed between the first movable element and the terminal. The first movable element causes the second movable element to cooperate with and at least partly expel the terminal from the cavity in the event the elastic lance fails to correctly engage the terminal.

A method for determining the color or color code of an object uses for example a color camera for making a color picture of the object. For a plurality of pixels of the color picture of the object distributed over the surface of the object, the S-, H- and B-values of the color picture are determined and the color is determined by comparison of these S-, H- and B-values with predetermined reference values. The B-value of each pixel is compared with a first reference value determining whether a pixel is black or not, whereafter, if the pixel is not black, the S-value of each pixel is then compared with a second reference value determining whether a pixel is colorless or not, whereafter, if the pixel is not colorless, the color of each pixel is determined by means of the H-value.
摘要:
A female electric terminal made of conductive sheet metal. The terminal has a contact body with contact first and second flexible blades which project from opposite walls of the contact body and which cooperate with a male terminal and a portion for connection to an electric cable. The blades define a gap smaller than the thickness of the male terminal. The male terminal is inserted into the gap and the blades cooperate elastically with opposite faces of the male terminal. The first and second blades are asymmetrical so as to define transversely offset contact areas on the respective faces of the male terminal.

A temporary locking device for locking the base of a floating base type connector comprises a pair of jaws, each actuated by a control member. The latter comprises a pedal operating through the intermediary of a finger on a drive piston having two notches defining locked and unlocked stable positions of the jaws. The finger operates also on a cam whose head engages in the notches. The device also comprises a manual resetting knurled wheel. Applications include space applications.
摘要:
A connection assembly comprising at least two superposed connection elements, i.e., an upper and a lower element, respectively, each of which comprises a housing, a central insulating body and a plurality of curved contacts arranged in the central insulating body, as well as stacking brackets which hold the connection elements in a determinate nominal superposed position. The stacking brackets are constituted by plates comprising an upper part incorporating a first position-retention element forcibly inserted into the upper connection element so as to form an attachment, and a lower part comprising a second position-retention element forcibly inserted into the lower connection element so as to form an attachment.
